It's harder than Black temple and is designed to be where you go after you have finished or almost finished that.

As this is a trash drop you might be able to get it with gladiatior gear but you would need a raid group even to deal with the trash.

I have heard about people farming the 1st trash pack with a small group... they apparently used 5 or so mages then just sheeped everything before killing 1 mob at a time. They leave the last mob sheeped then exit the instance. Leaving the sheep and then exiting and re entering means the whole trash pack respawns and you can the basically repeatedly farm the trash pack till you get the drop / drops you want.
